Series-Section Xmission Line Impedance Matching

Hi,
I would like to cut a 75 ohm coaxial cable to 30 electrical degrees at 7.2
Mhz. for use in a series matching section. The velocity factor of the cable is
not known. I have an Antenna Analyzer, and and RFsignal generator + the usual.

The impedance of the coax is stamped on the jacket, any way to determine 30
degrees without guessing at the VF?
